Description

Technical Field

[0001] This invention relates to the field of optical module sealing and protection technology, specifically to an optical module sealing and encapsulation protection structure. Background Technology

[0002] Optical modules typically contain sophisticated photoelectric conversion devices (such as lasers (LDs) and detectors (PDs), integrated circuit chips (such as driver chips and amplifier chips), and intricate structures like optical lenses. These components have extremely high requirements for the stability of their operating environment, and are particularly sensitive to moisture, dust, salt spray, and thermal stress caused by temperature changes. Once external moisture or contaminants penetrate the module, it can lead to optical interface contamination, metal contact corrosion, or short circuits, resulting in decreased optical power, reduced signal-to-noise ratio, and even permanent module failure.

[0003] Currently, the mainstream optical module packaging methods in the industry lack adequate protection, especially during the packaging process, where the optical module's interface is not protected and there are no effective clamping measures for the optical module.

[0004] However, the existing optical module sealing and packaging process does not provide adequate protection for its interface and cannot effectively clamp the optical module, which can lead to instability in the packaging. Therefore, we propose a protective structure for optical module sealing and packaging. Summary of the Invention

The spacing air rod 14 is used to drive one set of laser welders 13 to be mirror-symmetrical about the central axis with the other set of laser welders 13. An electrically rotatable temperature detector 15 is fixedly connected to the surface of the transverse frame 8. The temperature detector 15 is used to detect the temperature of the sealed weld joint.

[0035] The protective module 3 includes a guide air rod 31 fixedly connected to the surface of the support plate 1. A sliding block 32 is slidably connected to the surface of the guide air rod 31. A first connector frame 33 is detachably fixedly connected to the surface of the sliding block 32. A plug-in module 34 is connected to the end of the first connector frame 33. The plug-in module 34 is used to seal and protect the interface of the optical module. An adjustment module 35 is connected between the plug-in module 34 and the first connector frame 33. There are two sets of plug-in modules 34. The adjustment module 35 is used to adjust the two sets of plug-in modules. The spacing between groups 34, the number of guide rods 31, sliding blocks 32 and first connecting frame 33 are three groups, and the angle formed by the middle group and the other two groups is 90°. The end surfaces of the other two groups of first connecting frame 33 are provided with inner grooves 36. The inner side of the end of the first connecting frame 33 is slidably connected to a movable plate 37. The outer surface of the movable plate 37 is fixedly connected to a limit plate 310. A miniature shock absorber 38 and a second jacking spring 39 are respectively connected between one side of the movable plate 37 and the inner wall of the first connecting frame 33.

[0036] The plug-in module 34 includes a movable block 341 slidably connected to the outer surface of the first connecting frame 33. The surface of the movable block 341 is provided with a recessed groove 342. A first actuating spring 343 is provided inside the recessed groove 342. A movable block 344 is slidably connected to the inner side of the first actuating spring 343. One end of the movable block 344 is fixedly connected to a plug connector 345. The adjustment module 35 includes a sliding groove 351 opened on the outer surface of the first connecting frame 33. A sliding strip 352 is fixedly connected to the surface of the movable block 341. A fixed frame 353 is fixedly connected to the inner surface of the first connecting frame 33. A miniature electric cylinder 354 is fixedly connected to the surface of the fixed frame 353. There are two sets of miniature electric cylinders 354. The output ends of the two sets of miniature electric cylinders 354 are respectively fixedly connected to the two sets of movable blocks 341 with a second connecting frame 355.

[0037] The sliding block 32 slides along the length of the guide rod 31, and the movable plate 37 slides back and forth along the opening of the inner groove 36. The number of miniature shock absorbers 38 and the second-stage jacking spring 39 are several sets, all arranged in a straight line. The ends of the miniature shock absorbers 38 and the second-stage jacking spring 39 are fixedly connected to the movable plate 37 and the first connecting frame 33, respectively. The limiting plate 310 has a transverse "convex" shaped cross-section. The optical module is clamped and fixed by the two sets of limiting plates 310. The vibration and displacement of the optical module during the packaging process are reduced by the second-stage jacking spring 39 and the miniature shock absorbers 38. The first connecting frame 33 is connected and fixed to the sliding block 32 by bolts. The two ends of the spring 343 are fixedly connected to the inner wall of the movable block 341 and the movable block 344, respectively. The movable block 344 slides back and forth along the length of the opening of the recessed groove 342. The plug 345 matches the plug interface of the optical module, and the movable block 344 matches the outer opening of the plug interface of the optical module. The sliding bar 352 matches any section of the same length of the slide groove 351. There are two sets of sliding bars 352 corresponding to one set of slide grooves 351. The sliding bar 352 slides back and forth along the length of the slide groove 351. The position is adjusted by extending and retracting the micro electric cylinder 354. The two sets of micro electric cylinders 354 are parallel structures and their output directions are opposite.

[0038] In this embodiment, when the optical module and its package are located in the center processing part of the protective module 3, the first connecting frame 33 corresponding to the limiting plate 310 moves through the sliding block 32, so that the two sets of limiting plates 310 move closer to each other, so that the optical module is lifted above the limiting plate 310 and gradually clamped. At this time, the second top spring 39 and the micro shock absorber 38 will retract a certain distance until the position of the optical module is stable. Then, the first connecting frame 33 is moved by the sliding block 32 corresponding to the plug module 34 until the plug connector 345 is fully inserted into the plug interface of the optical module. At this time, the first top spring 343 is in a taut state, which keeps the plug interface of the optical module from being disturbed by the outside.

[0039] After the optical module is stabilized and protected, the operation of the horizontal air bar 7, vertical air bar 9, longitudinal air bar 10, adjusting air bar 11, and spacing air bar 14 is used to align the laser emitting heads of the two sets of laser welders 13 with the positions on both sides of the optical module that need to be welded. Then, driven by the horizontal air bar 7, the laser of the laser welder 13 slowly encapsulates the positions on both sides of the optical module that need to be welded and packaged, thus completing the encapsulation of the optical module. The welding process is parallel weld seam welding.

[0040] During use, when it is necessary to block and protect the interfaces of optical modules of different sizes, the distance between the two sets of plug-in modules 34 can be increased by extending the two sets of miniature electric cylinders 354, thereby achieving the purpose of adjusting the distance size. This can be used for the encapsulation and protection of optical modules of different specifications. In actual use, different No. 1 connector 33 can also be replaced to replace the adjustment module 35 and plug-in module 34 of different specifications.

[0041] Example 2, as Figures 8-11 As shown, based on Embodiment 1, a heat dissipation structure 4 is also proposed, including a heat sink block 41 penetrating through the support plate 1. A connecting groove 42 is provided on the upper surface of the heat sink block 41. A fixing block 43 is fixedly connected to the back of the support plate 1 near the connecting groove 42. A heat dissipation plate 44 is fixedly connected to the surface of the fixing block 43. A cooling fan 45 is fixedly connected to the back of the support plate 1 near the heat dissipation plate 44. An adjusting frame 46 is fixedly connected to the lower end of the heat sink block 41. A fixing column 47 is fixedly connected to one end of the adjusting frame 46. A sleeve column 48 is connected between the fixing column 47 and the support plate 1. A vertical cylinder 49 is connected between the other end of the adjusting frame 46 and the support plate 1. A heat dissipation assembly 40 is connected between the surface of the heat dissipation plate 44 and the support plate 1. The heat dissipation assembly 40 is used to enhance the heat dissipation of the heat dissipation plate 44.

[0042] The heat dissipation assembly 40 includes a connecting plate 401 slidably disposed on the surface of the heat dissipation plate 44. Vertical plates 402 are fixedly connected to the surface of the connecting plate 401. Several sets of vertical plates 402 are fixedly connected to the surfaces of these sets of vertical plates 402. Connecting frames 403 are used to connect the sets of vertical plates 402. One end of the connecting frame 403 is connected to a moving cylinder 404. A positioning frame 405 is fixedly connected between the moving cylinder 404 and the support plate 1. The other end of the connecting frame 403 is fixedly connected to a movable column 406. A guide frame 407 is connected between the movable column 406 and the support plate 1. A heat sink 41 penetrates the heat dissipation plate 44, and the heat sink 41 is slidably connected to both the heat dissipation plate 44 and the support plate 1. The diameter of the fixed column 47 matches the inner diameter of the sleeve column 48, and the two are slidably connected. Airflow is dissipated by the cooling fan 45. The heat sink 44 is used for heat dissipation. There are several groups of heat sinks 44 arranged in an array. The position of the heat sink block 41 is adjusted by extending and retracting the vertical cylinder 49. The heat sink block 41 and the adjusting frame 46 are kept stable by the fixed column 47 and the sleeve column 48. The connecting plate 401 has a U-shaped structure. The relative position between the connecting plate 401 and its upper components and the heat sink 44 is adjusted by extending and retracting the positioning frame 405. The heat dissipation efficiency of the heat sink block 41 is adjusted by adjusting the position of the vertical plate 402. The guide frame 407 is fixedly connected to the support plate 1. The movable column 406 passes through the guide frame 407 and the two are slidably connected. The connecting groove 42 matches the protruding part of the lower surface of the limiting plate 310. The heat is guided to the heat sink block 41 for heat dissipation by the limiting plate 310. Both the limiting plate 310 and the heat sink block 41 are made of thermally conductive materials.

[0043] In this embodiment, after the two sets of limiting plates 310 clamp a set of optical modules, the vertical cylinder 49 retracts. At this time, the adjusting frame 46, together with the heat sink block 41 and the fixing column 47, moves upward until the connecting groove 42 on the heat sink block 41 matches and engages with the limiting plate 310, thereby completing the fit. During the sealing and encapsulation process of the optical module, heat can be effectively conducted through the limiting plate 310 and the connecting groove 42, and then the heat dissipation fan 45 blows the heat dissipation plate 44, thereby completing effective heat dissipation.

[0044] During the heat dissipation process, when it is necessary to adjust the heat dissipation efficiency, the connecting plate 401 can be moved outwards towards the heat sink 44 by extending the moving cylinder 404, thereby increasing the area of ​​the heat dissipation structure 4 that acts as heat dissipation fins. Combined with the blowing of the cooling fan 45, the heat dissipation efficiency can be effectively improved. In actual use, the heat dissipation effect can be adjusted according to the feedback of the temperature detector 15. During this process, it should be noted that the connecting plate 401 needs to overlap with the heat sink 44 by a certain distance. As the overlap distance decreases, the thermal conductivity between the two will also decrease. Therefore, it is recommended that the minimum overlap area between the connecting plate 401 and the heat sink 44 should not be less than one-fifth of the area of ​​the connecting plate 401 to ensure the thermal conductivity between the two.

[0045] In summary, the specific operating principle of this invention is as follows:

[0046] During use, when the optical module and its package are located in the center of the protective module 3, the first connecting frame 33 corresponding to the limiting plate 310 moves through the sliding block 32, so that the two sets of limiting plates 310 move closer to each other, so that the optical module is lifted above the limiting plate 310 and gradually clamped. At this time, the second top spring 39 and the micro shock absorber 38 will retract a certain distance until the position of the optical module is stable. Then, the first connecting frame 33 is moved by the sliding block 32 corresponding to the plug module 34 until the plug connector 345 is fully inserted into the plug interface of the optical module. At this time, the first top spring 343 is in a taut state, which keeps the plug interface of the optical module from being disturbed by the outside.

[0047] After the optical module is stabilized and protected, the operation of the horizontal air bar 7, vertical air bar 9, longitudinal air bar 10, adjusting air bar 11, and spacing air bar 14 is used to align the laser emitting heads of the two sets of laser welders 13 with the positions on both sides of the optical module that need to be welded. Then, driven by the horizontal air bar 7, the laser of the laser welder 13 slowly encapsulates the positions on both sides of the optical module that need to be welded and packaged, thus completing the encapsulation of the optical module. The welding process is parallel weld seam welding.

[0048] During use, when it is necessary to block and protect the interfaces of optical modules of different sizes, the distance between the two sets of plug-in modules 34 can be increased by extending the two sets of miniature electric cylinders 354, thereby achieving the purpose of adjusting the distance size. This can be used for the encapsulation and protection of optical modules of different specifications. In actual use, different No. 1 connector 33 can also be replaced to replace the adjustment module 35 and plug-in module 34 of different specifications.

[0049] During use, after the two sets of limiting plates 310 clamp a set of optical modules, the vertical cylinder 49 retracts. At this time, the adjusting frame 46, together with the heat sink block 41 and the fixing column 47, moves upward until the connecting groove 42 on the heat sink block 41 matches and engages with the limiting plate 310, thus completing the fit. During the sealing and encapsulation of the optical module, heat can be effectively conducted through the limiting plate 310 and the connecting groove 42, and then the cooling fan 45 blows the heat sink plate 44, thus completing the effective heat dissipation.

[0050] During the heat dissipation process, when it is necessary to adjust the heat dissipation efficiency, the connecting plate 401 can be moved outwards towards the heat sink 44 by extending the moving cylinder 404, thereby increasing the area of ​​the heat dissipation structure 4 that acts as heat dissipation fins. Combined with the blowing of the cooling fan 45, the heat dissipation efficiency can be effectively improved. In actual use, the heat dissipation effect can be adjusted according to the feedback of the temperature detector 15. During this process, it should be noted that the connecting plate 401 needs to overlap with the heat sink 44 by a certain distance. As the overlap distance decreases, the thermal conductivity between the two will also decrease. Therefore, it is recommended that the minimum overlap area between the connecting plate 401 and the heat sink 44 should not be less than one-fifth of the area of ​​the connecting plate 401 to ensure the thermal conductivity between the two.

[0051] It should be noted that in actual use, the number of connecting slots 42 can also be set to multiple sets to meet the matching and bonding of optical modules of different sizes and specifications after the limiting plate 310 clamps them.

[0052] It should be noted that in practical applications, the cooling fan 45 can be set to a variable frequency to effectively adjust different cooling effects.

[0053] It should be noted that in this invention, the driving and moving principles of the guide air rod 31, the horizontal air rod 7, the vertical air rod 9, the longitudinal air rod 10, the adjusting air rod 11, and the spacing air rod 14 are all the same. They can be pneumatically driven, screw-driven, or other moving methods. However, while maintaining their basic moving performance, they should all have a certain degree of heat resistance. At the same time, the springs, seals, and other structures involved should all be made of materials with certain heat resistance to ensure that some of the temperature is dissipated during the packaging of the optical module, while still maintaining their respective performance.

[0054] It should be understood that in this application, all rotating, sliding, meshing, belt-driven and other moving parts are well lubricated and not prone to slippage or wear, and each part is provided with a corresponding protective shell. However, in the accompanying drawings of this application, the connection state of each moving part is not shown. It should also be understood that all parts in this application are made of metal or plastic materials with suitable strength in the relevant field to ensure that their structural rigidity meets the actual requirements.

[0055] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
